? . Only one specimen is known. It represents possibly a separate genus, for 

 which the name Exedrium (1888) as defined by ISmitli, I.e., will have to be retained. 

 We do not see any necessity, at present, to keep halicarniae geuerically separate. 

 Strecker's figure is quite insufficient to base a genus upon ; the specimen recpiires 

 examination as to structure.

J. Antenna long (tip broken off in the three specimens seen), distinctly 

 narrowed at the base, the segments not touching one another ventrally, middle ones 

 feebly dilated laterad subdorsally, almost as long as high, transsection little higher 

 than broad. Pilifer with brush of bristles. Palpus small, rough. Tongue short. 

 Tibiae )iot spiny ; spurs very short, proximal pair of hiudtibia al)sent ; no pulvillus, 

 paronychium very small, without lobes ; first segment of foretarsus with four long 

 spines, the apical one nearly half the length of the segment, second segment as 

 long as the first. 



Tenth abdominal tergite (PI. XXVI. f 34) narrow, curved, pointed, compressed ; 

 sternite broad (PI. XXVI. f. 35), obtuse, feebly sinuate at end. Harpe (PI. XXV. 

 f. 17) narrow, without patch of modified scales, subdorsal fold of inner surface high, 

 with bristles ; harj^e simple, not dentate, ending in an obtuse process. Penis-sheath 

 (PI. XXVIII. f. 47) thin, prolonged into a flat, feebly concave process curving side- 

 ways, ending in a very short pointed hook. 



? . Unknown. 



Larva and chrysalis unknown. 



Hah. North-West India. 



One species. 



A development from the ancestor of Hijloicus caligineus and oberthueri ; the 

 complete loss of the proximal ])air of sjiurs from the hindtibia is a noteworthy 

 character.
